I have several seroquil and ambien I am intrested in taking them for sleep purposes, But unfortunately I am tested 2 times a week using a 12 panel I-cup brand drug test, Anyone have past experience with this ,if I were to take the meds will I pass all drug tests or there is a possibility that I will give a false positive for benzos or TCA (Tricyclic Antidepressants) etc..

Seroquel (quetiapine) is known to interfere or cross-react with some immunoassays such as the one you mention.

See Univ of IL, Drug Information (http://dig.pharm.uic.edu/faq/2011/Feb/faq1.aspx)

Were these medications prescribed to you directly or did you get them from a friend for sleep purposes?
